I noticed the code seems to work if I use the layout “single Author” with big thumbnail picture. It does not work for “Raster-Layout (in German)”. What to do?

Thank you
I have replaced the file with the fixed one but in the footer are still loaded 450×450 images
I have tested in the development site where there is not caching plugin, varnish on different browsers with clean cache

I added then at raw 16
$avia_config[‘imgSize’][‘woocommerce_thumbnail’] = array(‘width’=>70, ‘height’=>70);

and now it works, but I don’t know if it would give problem in some other area of the site

Thank you

Hey Victoria,

thanks for your reply! I’ve found the right spot in postslider.php and could mod it successfully :)

Now I just have one further question: Can I put the modded postslider.php into the child-theme folder?

Best Regards,
Birger

If someone else is interested in the modded postslider.php, here’s the code (whole file):

<?php

 */
if ( ! defined( 'ABSPATH' ) ) {  exit;  }    // Exit if accessed directly

if ( !class_exists( 'avia_sc_postslider' ))
{
